MDVSA-2010:175

Problem description

A vulnerability has been found and corrected in sudo:

Sudo 1.7.0 through 1.7.4p3, when a Runas group is configured, does
not properly handle use of the -u option in conjunction with the -g
option, which allows local users to gain privileges via a command
line containing a -u root sequence (CVE-2010-2956).
